wiring my voltage guage, i no.. im a nub Options

[Nyczroflz]

hey guys i was just wondering on how to wire up my voltage guage... i removed the A pillar n noticed that were wires behind it, however they kinda have the color code of the radio wires, all i need is a constant voltage output and switch output. The wires are also really short so the only place i can wire them into is the radio wire looking thing. I was wondering how u guys did it it. Thanks

How many wires do you have? 1 wire for ground, 1 wire to hook up to your headlight switch and I assume u have 1 left to hook up to your power supply and feed it the signal right? So find the pwr supply of your radio when u turn the key on and hook it up to it. u can usually get rid of the headlight switch and leave it unhooked.
